To aZZwhom it may concern:

Be it known that I, JAMEs H. PETERSON, a

citizen of the United States, residing ork,in the county of others skilled in the art to which it appertains elevation. Fig. 3 is ont end view of the to make and use.the same, reference being tool looking in the direction of thearrowXin ad to e accompanying drawings, and to Fig. and Fig. 4 is a transverse section numerals of reference marked thereon, which taken on line 4 4 in said Fig. 1 looking in the orm a part of this specification. direction of the arrow Y.

's invention has reference generally to Similarcharacters of reference are employed in the said sponding parts.

eferring now to the said reference character 1 indicates scraping tool or views to indicate corremore par- 1 scraper which is es for use in scraping the hard 0 parquet floors, but whic in cabinetwork and other purposes he scraping of a surface is desired.

has for its principal objects simply-constructed which the handle is connected with the ade near and as closely to the scraping edge of the blade as is possible, whereby greater pressure can be brought upon the drawings, the the complete implement, the same comprising a suitable handle 2, with which is connecte a yoke or 0t 1er suitably-shaped blade-supporting secured against the usually ferruled end of the handle,

, as shown in Fig. 2 of v (1 frame 3 is also a pair of forwardly-extending 5, having holesor perforations ward ends for th 6 and 7. One of with a right-handed screw-thread 8, and the other screw 7 is made with a left-handed screw-thread 9. Pivotally arranged in the space between the said fingers or arms 5 is a supporting-plate 10, which preferably along its 1 g ,with'a pair of tubular ears or lugs 11, through wh' he respective pins or screws 6 and 7 he screw-threaded end portlons of said pins or screws 6 and 7 rojecting toward each other, substantially as shown in Fig. 3 of the drawings. The rethe drawprovided with her object of this invention is to pro- 1 scraping-tool in which the scrapblade is made very thin, being properly acked to prevent bending, said thin blade being readily tempered its scraping edge consequently being keptsharp for a being readily blade is adad usted position spective right and left handed screw-thread- Ot er objects of this inventlon not at this ed portions of said screws or pins 6 and 7 time more particularly mentioned Wlll b are respectively arranged in correspondinglyformed screw-threaded a nut or collar ent case being pressions 13 similar tool,

whereby the said nut or collar plement hereinafter set forth; and further- 2 may be turned to cause the said screwmore, this invention consists in t e various threaded portions of the said pins or screws arrangements and combinations of parts, as 6 and 7 to be drawn closer together or forced farther apart, according to the direction in fingers or arms IIO ' pair of below t e plane of the lower edges of the two adjustment vertically-adjusted relationupon the inner which said nut or collar 12 is turned. Thus it will be clearly evident that when the said pins or screws 6 and 7 are drawn toward each other the end portions of the two fingers or arms 5 of the frame 3 are made to bind against the ends of the respective ears or lugs 11 of the supporting-plate 10, whereby the latter can be secured and retained in any one of its adjusted positions, as clearly indicated in Fig. 1 of the drawings. The said being formed with a left-handed screwsupporting-plate 10 is also provided with a thread, a blade-supporting plate, said plate rearwardly-projecting perforated ears being provided with a pair of ivot lugs or or lugs 14, in which are arranged and suitears, through each one of Wl1l01 one of sai ably secured the respective end portions of screws extends, aright and left screw-threada rod or pin 15 The scraper-blade is indied nut between said pivot-lugs with w cated by the reference character 16, the said said screws are operatively connected, so blade being of suitable length and being that when said nut is turned, said fingers of placed against the inner face of the supportthe supporting-frame and the pivot-lugs will ing-plate 10, with the lower and knife or t into .binding relation, to hold scrapin edge 17 of theblade 16 extending the combination of a hanbe brough said supporting-plate rigidly in any one of its adjusted plane of the handle, and means for securing the scraper-blade in its adjusted position against the face of said supporting-plate, substantially as and for the purposes set forth.

, 2. In a scraper, the combination of a handle, a yoke-shaped blade-supporting frame comprising forwardly-extending fingers, each finger being provided with a screw-receiving perforation, a screw in of said screws being formed with a righthanded screw-thread, and the other screw being formed with a left-handed screw thread, a blade-supporting.plate, said plate being ,rovided with a pair of ivot lugs or ears, t rough each one of which one of said fingers or arms 5 That the said scraperblade 16 may be positively secured in its face of the supporting-plate 10 a holdingplate 18 is provided, said plate 18 having its lower marginal edge 19 arranged against the blade '16 and having its central portion resting upon the inner edge portion of the rod or pin 15, the binding or tightening relation ofthe holding-plate 18 being produced by a cone-shaped member or soc ret 20 and a screw or bolt 21, arranged in a screw-hole 22 in said socket or member 20. That the binding or holding pressure of the end portion of said screw or bolt 21 may be in a direction at right angles upon the face of the scraperblade 16, as indicated in Figs. 1 and 2 of the screws extends, aright andleft screw-threaddrawings, the said cone-shaped member or ed nut between said pivot-lugs with which socket 20 has a swivel-like motion in a corsaid screws are operatively connected, so

that when said nut is turned, said fingers of respondingly-formed hole 23 in the holdin plate 18, so as to move freely in said hole when the screw or bolt 21 is turned, thus causing the said socket or member 20 to adapt itself to the most efficient position and prevent any distortive movements of the parts during the act of tightening the scraper-blade 16 in its vertically-adjusted position upon the supporting-plate 10, as will be clearly understood.

From the foregoing description of my present invention it will be seen that I have devised a simply-constructed scraper tool or implement the scraper-blade of which is quickly and easily removed from the frame and handle of the tool for various purposes, and by the proper manipulation of the screw or bolt 21 and parts connected therewith the said scrape -blade is also easily brought into vertically-adjustable relation upon the inner face of the supportin -pl The scraper-blade 16 is also capa by the proper manipulation of the nut or collar 12, according to existing conditions in scraping a surface.
